' 'Be it known thatf LfRor-Di NnwBERRY, a citizen ofth e United States, residing at "Bronte, in the county of Coke and State 'of Texas, have invented certain new and useful Improvements "in Shock-Absorbers for Bicycles and Motor-Cycles'; and I do hereby declare thefollowing tobe a full, clear, and

v exact description of the invention, such as sorbing the: shocks and jars andincreasing "tlie 'life of a*-bicyc'le or -motorcycle' and of enabling the engine of the latter: to I run smoother-and at the expenditure of .less Pow I W'ith thes'ea' d other-"objects in viewthe invention consistsv in the construction-and novel combination and" -'arrangernent. of parts hereinafter fully-described, illustrated in the accompanying drawings and pointed out 'in the'cl'aiin hereto"appended; it being understood that various changes m n-1e form, proportion and minor details of construction may be resorted to Without departing from the spirit or sacrificing any of the advantages of the invention.

In the drawing Figure 1 is aside elevation of a bicycle provided with an attachment constructed in accordance with this invention,

Fig. 2 is an end elevation of a bicycle showing the attachment at opposite sides thereof.

Fig. 3 is an enlarged detail view of the attachment,

Fig. 4 is a detail sectional view illustrating the manner of connecting the upper and lower rods with the relatively slidable bear Fig. 5 is a detail view of the lower left hand rod illustrating the construction for connecting a coaster brake to the attachment.

Fig. 6 is a transverse sectional view through one of the cushioning devices.

, Like numerals of reference designate corresponding parts in all the figures of the dlawm 16,15155'. serial ma #1111 the accompanying drawing. in which is illustrated the preferredembodiment: of the invention, the-attachment which is shown applied to the frame 1 of abicycle at 0ppo-.

site sides thereof comprises in its construcv *tion, an arcuate; guide frame composed of I spaced front and rear sldes'2-andg3fand- Tconnectingiends 4 and 5 arranged at-the top andbottom of'tli e frame. .The ends 4 and 5 *are preferably formed integral with-front side-2 which consists ofa curved barprovided with av central enlargement orzlug 6. -;-The rear side 3 preferably consists of a curvedrod. having its terminals threaded .gandrextended through perforations 7 in the ends 4 and: 5, of the frame and secured to :the same bynuts 8 whichengage the threaded endsoftherod-orside 3. The arcuate ;.guide; framereceives a relatively; slidable bearing block 9- Iprovided witha bearing ,opening 10 for the reception of the axle ll :of the rear wheel l2o f the bicycle. jThe bearing block ;9 has a curved front edge 13 which fits against the curvedinner or rear andeis.slidable. along fthe same.

guide; block yis supported i andl h eld aug'ainst. lateral movement by upper and r I i lower-V rods 14,;and' .15.. extending through, 2- openi'ngs'16 and 17 in the ends 4' and 50f the guide frame. These rods 14 and15 have threaded inner ends 18 and 19 which are screwed into sockets or openings in the upper and lower ends of the bearing block 9 as clearly illustrated in Fig. 4 of the drawing. The outer ends of the upper and lower rods of the device at the right hand side of the bicycle are threaded at 20 and 21 for the reception of upper and lower nuts 22 and 23 and the lower end of the lower rod at the left hand side of the bicycle is provided with an arm 24. The arm 24 which is formed by'bending the rod upwardly and rearwardly is adapted to be connected with the arm of a coaster brake but when this is unnecessary both of the lower rods of the two devices may be threadedand provided;

at their lower ends with nuts. 7

The device is attached to the frame of the bicycle by a central clamp 25 consisting of t ers 2 e br ce the a j nt p rtion 9 secured to the lug 6 and the sides or 'fpor- 1 the e so" edge-of-the frontside 2 ofthegarcuate frame V Y upper and lower bracing arms 29' and 30- riveted or otherwise secured at their inner V 0691650! this patent may be -obtained zfor or rear ends to 'the'frame of the device and provided at their front endswith attaching portions 31 and 32 set at an angle and secured to the frame of the bicycle. The anguor other suitable fastening means. By this construction the frame may be quickly attached to the frame of a bicycle without requiring special tools. The upper rod 14: has disposed on ita coiled cushioning spring 33 interposed between the end 4 at the top of the guide frame and the upper edge of the sli'dable bearing block and adapted to -yield ably support the rear portion of the frame of the bicycle and adapted to absorb the shocks and jars and thereby increase the spring action of both the tire of the Wheel and spring of the seat. This enables the riding of bicycles and motorcycles to be much easier on both the machine and the person and the life of the machine is main the opening of the arcuate guide frame means of: a clip 34 of approximately bers of the bar, a bearing block slidably fitted against the inner side of the arcuate bar and provided with a central aperture adapted to receive the.axle of a rear wheel,

an arcuate rod slidably fittedthrough each opening of each end member of the bar, the inner end of each arcuate rod being screw threaded and fitted, into theopposite ends of the bearing block, means on the outer end ofv each rod for'limiting the movement of the rods with relation to the end members ofthe bar, a coiled spring surrounding one of said rods and herring" against the block and one vend'member, and a guide secured to the opposite side faces of the bearing block and embracingthe first named arcuate. rod to guide the bearing, block in its movement in the frame.
